Speech Title: Specifications for STOKIS – Official Topographic and Cartographic Information Ssystem of the Republic of Croatia
Speech Abstract: The first part of the STOKIS project refers to the development of product specifications that are the result of the STOKIS project, namely TK25 (Topographic Map 1:25 000), TK50, TK100 and TK250. The project started on October 21, 2019 and lasted until the end of June 2020. To begin with, it should be noted that data (which can still be used in specifications to establish the STOKIS system) were previously collected in CAD format for each sheet separately. The basic source of all topographic-cartographic data and products are photogrammetric mapping data (restitution data) and other originals. These data are topologically processed, classified according to the CROTIS data model, and finally stored in the TTB. Topographic data for individual topographic databases (TBP) of smaller scales are performed by performing model generalization, in such a way that for each subsequent TB of smaller scales, model generalization from previously established TB of larger scales is performed. The purpose of the Product Specification is to ensure the appropriate quality to produce topographic data (TP) mapped from in this case our TTB (Basic Topographic Database) but also from other originals. A comprehensive document describing the quality elements as well as the tolerances described in this specification are the basis for quality control. The product specification describes the technical characteristics of the topographic data, and how this data should be collected and processed. In addition to the technical characteristics, this document also describes the content and format for data delivery. The product specification should also reflect the requirements for the use of topographic data. User needs will be the basis for future development and changes in product specifications are focused primarily on user needs (and their changes in use reflected in the product) more efficient methods / processes in production (new technology) and according to international and OGC standards, DIGEST standards Everything serves to make these products easier to read, more up-to-date and more usable in practical application.

Speech Title: Energy Saving in High Inertia Building by Night Natural Ventilation in Hot Arid Climates
Speech Abstract: The thermal comfort and air quality inside buildings spaces is much recommended in Nowadays for human’s health and environment protection, especially if the inside comfort conditions are assured by passive systems means. In hot dry climate such Laghouat city in the south of Algeria, the first consideration in architecture design is given to the building envelope referring to the vernacular architecture in the region. The buildings with high thermal inertia envelope ensure the inside thermal comfort while it is properly closed during day time when the outside air temperature is very high, in hot dry region the night outside air temperature varies between 15 to 20°C, the night natural ventilation through windows properly oriented and dimensioned can lower the inside air temperature during night and evacuate the polluted inside air. The low inside temperature during night leads to a low inside temperature during day time, which has a good effect on energy saving during summer period where air conditioning is needed for more than seven months per year in this region. The present paper aim was to examine the impact of night natural ventilations in high thermal inertia buildings on energy saving, firstly a field work was carried out by measurements of inside air temperatures in two identical rooms of an old hotel called Marhaba with high thermal inertia envelope built with local materials. In first room the night natural ventilation allowed when the outside temperature was lower than the inside one by opening windows and the other room was closed around the clock. Secondly a numerical simulation was carried out to evaluate the field measurements results to choose the accurate software for further simulations in order to find the appropriate windows orientation, dimensions and positions can give the high energy saving performances in buildings with high thermal inertia envelope in hot dry climate.
